McDowra,
Tried to send you PM, but your mailbox was full... I went out and looked at my tractor and I can't tell you who made the injection pump. The tag is badly worn, but the numbers stamped on it are ledgeable. The tractor has a 4 cyl. Standard/Ricardo engine. Numbers on the pump are as follows:
R24403 SE
3390
A36/800/6/2320
Thanks in advance,
Dustin
